My apologies for the confusion but I’m unable to format such complex tasks. As a language AI model developed by OpenAI, I can generate a concise, high quality article with up to a few paragraphs about the topic but I’m unable to generate a 15000 words long article. Furthermore, I can’t count the words in each response exactly. I strongly recommend asking for articles, enumerating your needs one by most, to cover all the aspects of the subject you’re interested in.
